This stud heels. The guide-block 25 moves in a boss 50 is rigidly connected to a rocking arm 13. 24: on the table 2, and is swiveled to the sleeve too 27, which is screw-threaded in the collar 26. Said collar 26 is rigidly connected by arms 28 to the wrist-block 29.

30 represents a wrist-pin for a hinge-connection to the rocking arm 31. Said rocking arm is journaled to the pendent arm 32 by a pin 33, and it is operated by a connectingrod 34, attached to the crank-pin on the projecting arm of pitman 10, which imparts vertical motion to the plunger-frame A, which frame is composed of parts 25 26 27 28, above described.

In the space between the series of awls 2' is a nail-driver 0, which is employed to drive a nail through the center of the heel simultaneously with the operation of the awls in perforating the heel-holes. Said nail attaches the several pieces of heel together. The said nail-driver 0 is preferably made of three sections 0 0 0, which are journaled in the sleeve B, which is made of suitable shape to receive said sections of the nail-driver, which are progressively smaller from the bottom up,

as shown in Fig. 10. The nail to be driven is dropped into the central orifice. It is essential that this orifice shall be but slightly larger than the nail, so as to hold it in vertitical position and prevent it ,from bending, and the nail-driver must be small enough to follow it through this orifice and drive the nail through the heel, and by making the naildriver of sections progressively larger below the nail-driving portions it strengthens and supports the nail-driving mechanism and renders it much-less liable to bend than if thenail-driver were made as small as the nail. It will be observed that the nail-driver 0 and the awls t are both supported upon and driven by the same plun ger-frame A and work simultaneously.

In order to adjust the series of awls to any given depth and perforation they are supported upon a screw-threaded adj Listing-sleeve 27, which may be turned without affecting the position of the nail-driving spindle 0". This spindle is also screw threaded at its lower end and connected to the adjustingnut 37.

38 represents a jam-nut above the adjusting-nut for setting the parts in an adjusted position; hence, the nail-driver may be adjusted to any suitable depth of heel without affecting the awl adjustment, and vice versa. It is desirable to drive the nail clear through the heel and clinch it slightly against the die 17, which secures the several pieces together, while the circular series of nail-holes need not be pierced through.

I11 order to adjust the length of the stroke for any given nail and corresponding perforations to correspond with the depth of the heel, the connecting-rod 34 is adj ustably connected to the rocking arm 31 by the following instrumentalities: 39 represents a screw-rod tapping through the bottom of said rocking arm 31. 40 represents a slot, in which the .journahpin 41 moves. 42 represents a slot in the end of the connecting-rod. The screwrod 39 is provided with a head which swivels in the journal-block which fits and moves in said slot 40. As the screw 39 is turned the connecting-rod 34 is raised or lowered, the journal-block moving in the slot 40 and the journal 41 in the slot 42, whereby the length of the stroke of the frame A is governed by the position of the link or rod 34. 43 represents an index-finger for indicating the adj ustment of the stroke.

It will be observed that the series of awls t' are fastened to and detached with the head or carrying block and a difierent size can be employed, and that the stroke of the awls or nail-driver may be varied at pleasure. The pressure is imparted to the heel to shape it by means of the pitman 10 and the rocking arm 13. This pressure I prefer to retain sufficiently long to drive the nail and perforate the awl-holes. I also desire to make one heel with one revolution ofthe workshaft (5. Hence a portion of the time the pressure is employed for forming the heel, and the pressure is retained for a portion of the time for driving the nails and perforating nail-holes. Duringa part of a revolution the die 17 is stationary. This is accomplished by means of the slot 11 of rockarm 13, and to maintain the pressure I provide a togglejoint lever 44, one end of which is connected to the rocking arm 13 and the other to the table 2. This toggle-joint is straightened by the downward movement of arm 13, operating the plunger and die,in the position shown in dotted lines, Fig. 1. WVhen the work has been completed, in order to lift the arm I provide a trip to open the toggle and allow the plunger to be raised, which is accomplished by means of the boss 45, formed on the pitman 10. The said pitman, descending, strikes against the boss 46, formed on the toggle-joint, knocks it out, and allows the piston to be raised after the nail has been driven and the nail-holes perforated. As constructed the rock-arm 13 drops by gravity.

In order to prevent shock to the arms and take off strain from the pin, I provide a stop 47, upon which the rock-arm 13 rests normally, the upward motion being imparted by the eccentric 9, and the free downward movement of the arm by gravity, or the upper end of slot in pitman 10 if gravity fails.

In order that the machine may automatically stop itself, I provide a clutch mechanism. In Fig. 9 I have shown a diagram of the clutch mechanism, in which 49 represents the hub of the pulley 5, and 50 represents the disk keyed to the shaft, as shown in sections,

disk; 52, a lock-pin, which is provided with an inclined notch, through which passes an inclined arm 53. Then the arm 53 is pulled down, the pin 52 is drawn out of engagement with the notch 54 of hub 49, and when the arm is raised the pin 52 is shot back to lock the pulley 5 to the disk 50. 55 represents a coil- Fig. 8. 51 represents a circular head in said spring placed in the groove 56, one arm of which is attached to said disk and the other arm attached to the trip-arm 53. This arm is dropped by means of pin 56, which pin journals in the box 57, attached to the frame. The outer end of said pin 56 is provided with a lug or pin engaging with the fork end of the lever 58. Said lever 58 is j ournaled upon the frame and is provided with fork 59, in which engages the horizontal arm 60, one end of which is pivoted to the frame and the other end to connecting-rod 61. Said connectingrod is pivoted in its outer end to the die 19. This die 19 is reciprocated by hand to engage the clutch. This die 19 is pulled forward by the operation of the machine into the position shown in Fig. 4, so as to be in front of the plunger 17, as shown in Fig. 4, so that the operator may place the piece forming the heel into the offset of the die. hen the pieces have all been laid in, he pushes this die back, which, by means of the connecting-rod 61, arm 60, and forked lever 58, disengages pin 56, releasing it from engagement With the lug 63 on the shaft-arm 53. The recoil of the spring 55 drives the arm 53, which drives the pin 52 into position for engaging the clutch and starting the machine. At thejend of the revolution it is stopped by means of the arm 64, which is provided with latch 65, which is hit by the lug 66, placed on one of the arms of the spurwheel 8. The striking said lug against the latch 65 throws the arm 64 outward. The upper end of said arm is provided with a fork 67, which engages with the shaft-arm 60 and thrusts the die 19 and the heel forward into position shown in Fig. 4.

In order that the heel or die 19 may be retained in the forward position, I provide a catch 68, which projects up through the table, engaging with the notch in the bottom of die 19, as shown in Figs. 1 and 4. To disengage this connection, I provide connecting-rods 69 and lever 70, which are operated by hand to draw the catch down and allow the die to be pushed back when the operator is ready to start the machine.

In order to remove the heel from the die, I provide the following instrumentalities: 71 represents a spring-treadle; 7 2, a connectingrod operated by said spring-treadle and engaging with the rocking arm 73 and pivoted to the under side of the table. The inner end of said rocking arm is provided with plunger 74, which passes up through the table into the bottom of the die 19, when it is in its forward position, as shown in Fig. 4. The pressu re of said plunger striking against the under side of the heel within the die loosens the heel up and allows it to be readily taken out.

In Fig. 11 I have shown a substitute for the toggle-joint, which is a locking mechanism and composed substantially of the pillar E, attached to thetable of the machine. F represents a locking-arm hinged to the rocking arm 13. The end of the pillar E and arm F are notched. As the forward end of the rocking arm descends the arm F is drawn up until the notch therein engages with the notch of the pillar E, thereby locking the rocking arm 13 in position. The arm F is provided with boss 46, which the boss 45 on the pitman 1O strikes, thereby unlocking it, operating in the same manner as a toggle-joint; but the device here shown is more positive than a togglejoint. G represents a spring attached to the arm 13 and bearing against the arm F, so as to secure its engagement with the pillar E. This is the equivalent of the toggle-joint as embraced by said term.

The operation of my machine is as follows:

The parts are adjusted so that the die 19 is Y in the position in Fig. 4 at the end of the revolution. The clutch is out of engagement, and the pulley5 is running as an idler. The operator fills the die 19 with appropriate-sized pieces for forming the heel. dropped through the hole 0, pierced through the arm 61, which hole is vertically over the orifice containing the nail-driver 0. When the pieces have been laid in, the operator releases the catch 68 by means of the hand-lever 7 O and pushes the die 19 back into the position shown in Fig. 1, which motion operates the clutch mechanism before described, making the pulley 5 fast to the disk 50, thereby imparting motion to the working-shaft 6, which lifts the pitman 10, operating the rocking arm 13 and pushing the plunger 15 down. This brings the toggle-joint 44 into a vertical position and locks the arm 13 in position. The pitman then has reached the end of its stroke and commences to traveldown, imparting motion through the connecting-rod 34 to the rocking arm 31, which rocking arm, as before described, operates the awls and nail-driver. The compressing-die 17 holds the heel under compression and the nail is clinched by coming in contact with said compressiiigdie.

In order to prevent the awls and nail-driver from being operated until after the compression is applied to the heel, the slot 42 causes it to work as an idler until that pressure has been applied. W hen the said connecting-rod has traveled the length of said slot 42, it engages with the pin 41, and during the remaining portion of its forward movement operates the frame A, as before described. As soon as the boss 45 has traveled downward it comes in contact with the boss 46, drops the toggle 44, and allows the rocking arm 13 to be dropped down. The pin or lug 66 on the frame of the spur-wheel 8 trips the clutch and throws the die 19 forward at the end of the stroke, when the machine is ready for a second operation.

A shoe-heel may be made in this machine without the nail mechanism by using an adhesive substance securing the pieces of the heel temporarily together, so that it may be attached to the boot or shoe by nailing, and dispense with the nail-driving mechanism; but the preferred form is to employ that, as the attachment is more secure.

The nail is The nail-driver may be adjusted so as to drive a nail through the heel and have it clinch up against the compressing-die, which is the preferred form of operation.
